FINISHING-MACHINE.

Application filed March 2 191?.

To all whom it may concern.

Be itknown that I, HARRY W. Lows, a citizen of the United States,residing at Omaha, in the county of Dt'iuglas and State of Nebraska.have invented new and useful Improvements in 1*inishing-h iachines, ofwhich the followin a full, clear, concise, and exact description,reference being had to the accompanying drawing, forming a part of thisspecification.

My invention relates to finishing machines and more specifically tofinishing machines for catsup.

One of the objects of my invention is to provide an improved finishingma chine for catsup, or the like, which will not force foreignSlll)t111(i6$. such as mold and the undesirable parts of the tomatoessuch as the harder reen portions, through the screen, thereby insuring asmooth uniform high grade product. Further objects will appear from thedetail description to follow and from the appended claims.

In the dra *ings in which one embodiment of my invention is shown:

Figure l is a vertical axial section through a finishing machineembodying my invention.

Fig. 2 is an end elevation of the machine viewed from the left of Fig.1.

Fig. 3 is a plan view of the machine.

Fig. at is a detail sectional view showing the location of the brushwith respect to the screen.

Fig. 5 is a section on the line 5-5 of Fig. 1.

Fig. (5 is a detail view of the spider which actuatcs the brushes.

Referring now to the drawings in detail, the finishing machine shown,comprises a perforated frusto conical screen 10 whlch may be of sheetbrass, a nest of brushes, 11, pivotally mounted to operate in saidscreen, to force the material hrough the perfora tions of the screen,means 12 for. rotating said brushes, means, 13, for supplying thematerial to said screen, refuse collecting and discharge means 13 fordisposing of the material which is not forced through the screen by thebrushes, a bowl or tank 14: surrounding the screen 10 to receive thematerial forced through the perforations of the screen and a supportingframe or base 15, on which the various parts are mounted.

Specification of Letters Patent.

Patented Oct. 18, 1921.

Serial No. 156,489.

The screen 10 is closed at the bottom as indicated at 16 and is providedat its upper end with an annular frame 17 which rests on the ledge 18 ofthe annular channel member 19. This channel member 19 is provided withoppositely disposed trunnions 20 mounted in bearings 21 on the frame 15.I

Each of the brushes 11 is hingedly secured at to a brush ring 23. Thenest of brushes rest freely and pivotally in the conical screen 10.

The means 12 for rotating the brush ring with the nest of brushes.comprises a spider Ql, the arms of which engage with hook shaped lugs 26on the ring 23, a hollow shaft i i, to which the spider 2% is secured, abevel gear 28 secured on the shaft 27. a bevel pinion Q9 meshing withthe bevel gear 28, a shaft 30 on which the bevel pinion 29 is securedand a pair of fast-and loose pulleys 31 and 32 mounted on the shaft 30.As shown in Fig. 1, the engagement between the arms and the lugs 26 issomewhat loose. This permits the ring 23, and hence the brushes 11 toact as floating members when the arms are rotated, to enable the brushesto adjust themselves to the screen 10, this adjustment being furtherfacilitated by the pivotal connection at 22, which also acts to allowthe brushes to float to adjust themselves to the screen. The shafts 2-7and 30 are rotatably mounted in bearings 33, 34-, in the bearing bracket36, which is pivotally mounted on the frame 15 by means of a shaft orpin 37. This pivotal mounting of the bracket 236 permits the shafts 27and 30, with associated mechanism, to be swung up away from the nest ofbrushes and out of the conical. screen 10, to permit access to thebrushes and screen for cleaning, etc.

Themeans 13 for supplying the material to the perforated screen,comprise in addi tion to the hollow shaft 27, a tubular connection 38,threaded into the gear casing 39 and communicating with the hollow shaft27.

The refuse collecting and discharge means 1% comprise a refuse sweep l0operating in the channel member 19 and secured to one of the brushes,and a discharge chute 4C1, lead ing from a suitable opening 42, formedin the side of the channel member 19. The channel member 19 may beprovided with a suitable cover The bowl or tank 1 1 provided withoppositely located lugs H as follows: Power is applied to the fastpulley 31 by means of a dog causing the shaft 30 to rotate and with itthe metal pinion 29. This causes the rotation .of the bevel gear 28,hollow shaft 27, and spider 25, the arms of the spider 25 engage thehook shaped lugs 26, causing the rotation of the brush ring and nest ofbrushes.

Material such as tomatoes, from the pulping machine is supplied to thescreen 10, through the tubular connection 38 and hollow shaft 12. Thismaterial flows out between the brush and screen, and the brushes as theyrevolve, force the material through the perforations in the screen. Thebrushes are floatably mounted and bear on the pulp with a yieldingpressure so as not to force substances such as mold and the undesirableparts of the tomatoes, such as the hard green portion, through theperforations in the screen. The finished material forcer through theperforations in the screen 10 escapes into the bowl or tank lei and isdischarged through the opening The foreign substances and the harderportions of the tomatoes are gradually worked upwardly along the sidesof the screen 10 due to the action of the brushes, and centrifugalforce, and escapeinto the channel member 19. The refuse sweep 40operating in the channel member 19 sweeps the refuse along the channelmember and out through the opening 42 into the discharge chute 4E1.

In'working along the sides of the screen these foreign substances actsomewhat as a pressure mat between the brush and the surface of thescreen. In operation, the brush assumes a position such as shown in Fig.4, the lower part of the brush being farther from the screen than is theupper part of the brush. The result of this operation is that noundesirable substances are forced through the screen and the finishedproduct is of ood color and high quality.

Vhen it is desired to have access to the screen 10 or brushes 11, forcleaning purposes, etc, the spider 25 may be rotated slightly to free itfrom the hoolcshaped lugs 26, after which the bracket 36 can be swungabout the pin 37 to lift the shaft 27 and spider 25 away from thebrushes-l1. In doing this, it is, of course, necessary to disconnect thetubular connection 38. The nest ofbrushes can then be lifted out of thescreen and if desired, the screen and the channel member 19 may belifted out of the same to permitaccess to the bowl 14+.
